Unsteady Aerodynamics - Synchronized Flow Control of Dynamic Stall under Coupled Pitch and Freestream
Abstract
The proposed research seeks to conduct experiments with synchronized fluidic control to mitigate the adverse effects of dynamic stall and increase cycle average lift and reduce the moment spike typical of dynamic stall events. The proposal will conduct both mild and deep dynamic stall investigations at appropriate mean frequencies, Mach nwnbers and Reynolds numbers. Unsteady flow control will be implemented using vortex generating jets embedded within the surface of the test article. The effect of actuation amplitude, frequency, duty-cycle, and phase (relative to the motion) on the dynamic lift and moment curves will be examined. Time-resolved unsteady surface pressures, forces, and moments will be acquired.
